ICD-10 Code K80.1 – Calculus of gallbladder with other cholecystitis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K80.1 – Calculus of gallbladder with other cholecystitis
What it is
K80.1 identifies gallstones in the gallbladder when cholecystitis is also present, but not the acute form specified by other codes. Use it when documentation links gallbladder calculi with another type of cholecystitis.
Clinical signs
Clinical features vary; refer to documentation. Typical findings may include right upper quadrant pain, nausea, vomiting, and imaging or operative evidence of gallstones with gallbladder inflammation.
When to use this code
Use K80.1 when the record clearly states calculus of gallbladder with other cholecystitis, and the provider does not specify a different cholecystitis type. It fits cases where gallstones and inflammatory gallbladder disease are both documented. If the note only says gallstones, or the cholecystitis type is unclear, check documentation.
Do not use for
Do not use this code for gallstones without cholecystitis, or when the chart specifies acute cholecystitis or another more specific gallbladder condition. Check documentation if the diagnosis is incomplete.
Coding tip
Code the documented combination exactly; if the cholecystitis type is not stated, query the provider before assigning K80.1.
